We’re continuing here with the upper build process for the AR-MPR rifle. In this video, we’ll walk through the process of disassembling the barrel assembly, replacing the barrel nut with the custom aluminum unit that came with the Midwest Industries freefloat handguard, install the barrel, install the gas block and gas tube, and finally replace the muzzle brake. In the next video, we’ll install the handguard assembly.
Do you have tips or tricks that you want to share related to these assembly steps? Please comment on this post if so…
